Question

1. Calculate the force of gravity in newtons if your weight is 110 lbs?

2. In order for motion to occur, the net force is _______.

Answer 1

First of all you need to know that the force of gravity =m×g. In which, m is the mass and g is the gravitational constant, which is 9.81N/Kg. Since the constant is in Newtons per Kilograms, you need to have the mass in Kg. So your 110 lbs is approximately 49.89 Kg.

Now, just plug in everything in the equation.

F= m×g

F= 49.89kg×9.81N/kg

F= 489.4N

Hope this helps!

Answer 2

Given that,

mass m = 110 lbs

Force of gravity in Newton, F =?

Since,

1 lbs = 0.45 kg

110 lbs = 110* 0.45 = 49.5 kg

Since, force of gravity equals the weight of the body.

F = W = mg = 49.5 * 9.81

F = 485.595 N

Force of gravity will be 485.595 N.

In order for motion to occur net force is greater than 485.595 N.
